To fit the criteria for an AMBER Alert activation, a person must be under what age?

For an AMBER Alert activation, the criteria typically require that the missing person be under the age of 18 years old. This is consistent with federal guidelines and the intent of the AMBER Alert system, which focuses on the immediate recovery of abducted children.

When considering the age range mentioned in the question, individuals under 18 are recognized as minors, and AMBER Alerts are specifically designed to alert the public regarding child abductions. The system aims to disseminate information rapidly to mobilize community assistance in locating these vulnerable individuals.

The other age options provided exceed the established 18-year threshold and therefore do not align with the criteria that govern AMBER Alert activations. Understanding this age requirement emphasizes the system's primary focus on protecting minors, reinforcing the importance of swift action in these critical situations.
